Application filed February 23, 1922. Serial No. 538,780-.

Sacramento and State of California, have invented a new and useful Improvement in an Overtire, of which the following is a specification.

My invention relates to improvements in over-tires wherein a motor vehicle tire shoe or casing is cut through at one point toprovide two adjacent ends to interrupt the continuity of said tire and cut through the tread transversely and to the beads at regular intervals between said ends to provide a series of separate tread sections.

The primary object of the present invention is to provide a new and improved overtire for motor vehicles and the like.

Another object of the invention is to provide a new and improved over-tire adapted for application to the tires of a motor vehicle, which shall increase tractive facilities of said tires.

A further object is to provide a new, and improved device ofthe character set' forth having a series of tread sections which may be formed by cutting the tread of a sec ends tire at regular intervals through the bead portions thereof, and cutting said tire entirely through said section and heads at one point to provide two ends to facilitate the application of said over-tire to said tire.

A still further objectis to provide rein-' forcing means detachably connected to each section at each side thereof and embracing the adjacent bead portion whereby said tire sections may be more firmly connected to said head portions and also to provide means for replacing a worn section and suitably and firmly connecting it to the adjacent I also pro-vide a suitable means for detachably connecting the ends of the over tire to facilitate application and removal of said over-tire to a vehicle tire.

I accomplish these and other objects by means of the device disclosed in the drawings forming a part of the present specification, wherein like characters or reference are used to designate similar parts throughout the said specification and drawings, and in which:

Fig. 1 is a broken side elevation of a. mo-- tor vehicle tire disclosing my improved overtire applied thereto;

Fig. 2 is an enlarged sectional view of a tire or shoe, one-half of said' section being taken in mid-section, and the other half between sections, of the over-tire;

Fig. 3 is a broken plan View of Fig. 1; and

Fig. 4 is an enlarged broken detailed view ofaportion of one side of the over-tire, adjacent the two ends thereof, disclosing the manner in which one of the U-bolts is applied to detachably connect said ends.

Referring to the drawings the numeral 1 is used to designate in general an overtire comprising a casing separated at one point as at 2 to provide two ends and cut ranged to embrace the adjacent bead portions 1 and having their free ends extending radially to engage the sections 6. The shoes 7 are each provided with cent-rally disposed apertures 9 and are detachably secured to their respectivesections 6 by means of suitable bolts 8. v a

In order to efl'ectively and conveniently secure the two ends of the over-tire in position I have provided a pair of U-bolts 11 interposed between the over-tire 1 and the shoe or casing 12 of the motor vehicle with the free ends of said 'U-bolts 11' projecting outwardly through the apertures 9 of' the shoes 7 adjacent the said two ends, as dis closed in Figs. 1 and 4 of the drawings. To assist said U-bolts 11 a link 14: is provided having its ends apertured to receive the free ofthe drawings whereby the two ends of the over-tire 1 maybe drawn together to properly position said over-tire 1 upon the shoe or casing 12 of the vehicle; and to so holdsaid over-tire in position While the one oftheffree' ends of the U-bolt 11 is being inserted through its respective aperture 9 in the shoe 7 adjacent one of said ends of said over-tire 1.

' by the beads of the over-tire.

In this manner I have provided an 0vertire comprising a series of sections connected When any one of said sections 6 is cut or worn it may be cut away from the heads 4 and a new section inserted and secured in position by the adjacent shoe 7.

It should be noted that the metallic shoes 7 extend over the side walls of the shoe or casing 12 thereby protecting said side walls from cuts and bruises. The applicationof the over-tire also provides a deepened or thickened tread portion which will tend'to prevent punctures and stone bruises and wear of the shoe or casing 12. B reason of the separate sections 6'traction is facilitated and there is a tendency to prevent skidding. I

Having thus described my invention what I claimas new and desire to secure by Letters Patent is: j 1. An over-tire comprisinga casing separated atone point to provide two ends and cut at regular intervals between said ends through the tread and to the beads thereof to provide tread sections; and means for detachably connecting said ends to retain said over-tire inposition upon a vehicle tire.

2. An over-tire comprisinga casing separated at one point toprovidetwo ends and cut at regular intervals between said ends through the tread and tofthe beads thereof to provide tread sections; U-bolts connecting said ends and havingthe shank thereof interposed between said over-tire and a vehicle tire to retain saidbolts in engaging relation with said over-tire.

3. An over-tire comprising a casing separated at one point to provide two ends and cut at regular intervals between said ends through-the tread and to the beads thereof to provide tread sections; .U-bolts connecting said ends and having the shank each tread section to prevent separation of said sections fromthe beads.

5. An over-tire comprising a casing separated at one point to provide two ends and 'cut at regular intervals between said ends through thetread and tothe beads thereof to provide tread sections; separate reinforcing members detachably, connected to each tread section to prevent separation of said sections from the beads; and means for detachably connecting said ends to retain said over-tire in position upon a vehicle tire.

6. An over-tire comprising a casing separated at one point to providetwo ends and cut at regular intervals between said ends .throughi'theutread and'to the beads thereof to providetread sections; means for detachably connecting said ends! to. retain said OVQF-UI'G 1n position upona vehicle tire;

and shoes detachably connected to each'sec-- tion and embracing adjacent portions of the beads to prevent separation of said-seations fromsaid beads;

7. Anover-tire comprising a casingsep-- arated at one point to provide two'ends and embracing adjacent portions of 'the beads toprevent separation of saidsections from said beads, each of said shoes being:

provided with centrally disposed apertures for the engagement -of-a placing and re moving tool 'whereby said over-tire may :be r

placed and removed: I I

8. An over-tire comprisinga casing separated at one point to provide two ends: and cut transversely through thetr'ead to the beads thereof at regular intervals between said ends to provide tread sections; shoes-- detachably connected to each section and embracing adjacent portions of the "beadsto prevent separation of said sectionslfrom said beads; each of :said shoes being pro vided with centrallykdisposed apertures for the engagement of a placing-and removing v tool whereby said-'over-tire may be placed andremoved; and means for detachably ens gaging the ends of theiover-tire to secure I the same over a vehicle tire.

9. An over-tire comprising a :casing sep-.

arated at one point to provide'two ends and i cut transversely through-the tread 'to -the,

beads thereof at. regular intervals between said ends to provide. tread sections; shoesdetachably connected to each sectionand embracing adjacent portions ofthe beads to and removed; U-bolts detachably enga ing the centrally disposed apertures of the s oes adjacent theatwo ends of the over-tire; andmeans for engaging the free-ends of said' U-bolts to retain thesame in position to".-
